As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Xonsh Change Log
====================
v0.8.8
====================
**Added:**
* ``vox new`` has an added ``-p --interpreter`` flag for choosing the python interpreter to use for virtualenv creation
* The default Python intrepreter vox uses to create virtual environments can be set using the ``$VOX_DEFAULT_INTERPRETER`` environment variable.
**Changed:**
* ``lib.ChainDB`` now resolves results to the type of the inputs if possible
v0.8.7
====================
**Added:**
* New xonsh syntax ``pf`` strings -- combining path strings with f-strings.
Usage:
.. code-block:: bash
gil@bad_cat ~ $ repos = 'github.com'
gil@bad_cat ~ $ pf"~/{repos}"
PosixPath('/home/gil/github.com')
gil@bad_cat ~ $ pf"{$HOME}"
PosixPath('/home/gil')
gil@bad_cat ~ $ pf"/home/${'US' + 'ER'}"
PosixPath('/home/gil')
**Fixed:**
* Set ``ls`` to ``predict_true`` in ``default_threadable_predictors``. This prevents ``ls`` on OSX
from being flagged on OSX as unthreadable (incorrectly) because it relies on ``ncurses``.
v0.8.6
====================
**Added:**
* Doco about how to update xonsh and how to set and unset environment variables
**Fixed:**
* Updated behavior of the ``cat`` coreutils function so that it properly
handles as vareity of cases such as:
* Exits after concatenating normal files which have a finite size
* Continues to run for special files which do not have a size,
such as ``/dev/random``
* Is interruptable in all cases with Crtl-C.
* Callable aliases were not properly raising a ``CalledProcessError`` when they
returned a non-zero exist status when ``$RAISE_SUBPROC_ERROR = True``. This has
been fixed.
* Fixed interpretation of color names with PTK2 and Pygments 2.3.1.
v0.8.5
====================
**Added:**
* Add alias to `base16 shell <https://github.com/chriskempson/base16-shell>`_
* Installation / Usage
1. To install use pip
.. code-block:: bash
python3 -m pip install xontrib-base16-shell
2. Add on ``~/.xonshrc``
.. code:: python
:number-lines:
$BASE16_SHELL = $HOME + "/.config/base16-shell/"
xontrib load base16_shell
3. See image
.. image:: https://raw.githubusercontent.com/ErickTucto/xontrib-base16-shell/master/docs/terminal.png
:width: 600px
:alt: terminal.png
* New ``DumbShell`` class that kicks in whenever ``$TERM == "dumb"``.
This usually happens in emacs. Currently, this class inherits from
the ``ReadlineShell`` but adds some light customization to make
sure that xonsh looks good in the resultant terminal emulator.
* Aliases from foreign shells (e.g. Bash) that are more than single expressions,
or contain sub-shell executions, are now evaluated and run in the foreign shell.
Previously, xonsh would attempt to translate the alias from sh-lang into
xonsh. These restrictions have been removed. For example, the following now
works:
.. code-block:: sh
$ source-bash 'alias eee="echo aaa \$(echo b)"'
$ eee
aaa b
* New ``ForeignShellBaseAlias``, ``ForeignShellFunctionAlias``, and
``ForeignShellExecAlias`` classes have been added which manage foreign shell
alias execution.
**Changed:**
* String aliases will now first be checked to see if they contain sub-expressions
that require evaluations, such as ``@(expr)``, ``$[cmd]``, etc. If they do,
then an ``ExecAlias`` will be constructed, rather than a simple list-of-strs
substitutiuon alias being used. For example:
.. code-block:: sh
$ aliases['uuu'] = "echo ccc $(echo ddd)"
$ aliases['uuu']
ExecAlias('echo ccc $(echo ddd)\n', filename='<exec-alias:uuu>')
$ uuu
ccc ddd
* The ``parse_aliases()`` function now requires the shell name.
* ``ForeignShellFunctionAlias`` now inherits from ``ForeignShellBaseAlias``
rather than ``object``.
**Fixed:**
* Fixed issues where the prompt-toolkit v2 shell would print an extra newline
after Python evaluations in interactive mode.
v0.8.4
====================
**Added:**
* Added the possibility of arbitrary paths to the help strings in ``vox activate`` and
``vox remove``; also updated the documentation accordingly.
* New ``xonsh.aliases.ExecAlias`` class enables multi-statement aliases.
* New ``xonsh.ast.isexpression()`` function will return a boolean of whether
code is a simple xonsh expression or not.
* Added top-level ``run-tests.xsh`` script for safely running the test suite.
**Changed:**
* String aliases are no longer split with ``shlex.split()``, but instead use
``xonsh.lexer.Lexer.split()``.
* Update xonsh/prompt/cwd.py _collapsed_pwd to print 2 chars if a directory begins with "."
* test which determines whether a directory is a virtualenv
previously it used to check the existence of 'pyvenv.cfg'
now it checks if 'bin/python' is executable
**Fixed:**
* Fixed issue with ``and`` & ``or`` being incorrectly tokenized in implicit
subprocesses. Auto-wrapping of certain subprocesses will now correctly work.
For example::
$ echo x-and-y
x-and-y
* Fix EOFError when press `control+d`
* fix no candidates if no permission files in PATH
* Fixed interpretation of color names with PTK2 and Pygments 2.3.
* Several ResourceWarnings: unclosed file in tests
* AttributeError crash when using --timings flag
* issue #2929
v0.8.3
====================
**Added:**
* Dociumentation paragrapgh about gow to run xonsh in Emacs shell
**Changed:**
* Updated what pip requirements are needed to build the documnetaion
* ``$XONSH_TRACEBACK_LOGFILE`` now beside strings also accepts ``os.PathLike``
objects.
* Updated vended version of ``ply`` to 3.11
* Deprecation warnings now print from stacklevel 3.
**Fixed:**
* Annotation assignment statements (e.g. ``x : int = 42``) are now supported.
* Fixed error output wording for fg and bg commands
* Flake8 errors
* xonsh can now properly parse import statements with trailing comma within
parentheses, e.g.::
from x import (y, z,)
* ResourceWarning: unclosed scandir iterator in imphooks.py
* Removed use of deprecated ``inspect.formatargspec()`` for ``inspect.signature()``
* ``Makefile`` directive that updates vended version of ``ply``
v0.8.2
====================
**Changed:**
* Now there is only a single instance of ``string.Formatter()`` in the
code base, which is called ``xonsh.tools.FORMATTER``.
**Fixed:**
* f-strings (``f"{expr}"``) are now fully capable of executing xonsh expressions.
The one exception to this is that ``![cmd]`` and ``!(cmd)`` don't work because
the ``!`` character interferes with Python string formatting. If you need to
run subprocesses inside of f-strings, use ``$[cmd]`` and ``$(cmd)`` instead.
* Fixed occasional "no attribute 'settitle' error"
v0.8.1
====================
**Added:**
* ``SubprocSpec`` has a new ``pipeline_index`` integer attribute that indicates
the commands position in a pipeline. For example, in
.. code-block:: sh
p = ![ls -l | grep x]
The ``ls`` command would have a pipeline index of 0
(``p.specs[0].pipeline_index == 0``) and ``grep`` would have a pipeline index
of 1 (``p.specs[1].pipeline_index == 1``). This may be usefule in callable
alaises which recieve the spec as an argument.
**Changed:**
* Removed ``fish`` from list of supported foreign shells in the wizard.
* Circle CI config updated to use a pinned version of ``black`` (18.9b0)
* Pytest plugin now uses ``xonsh.main.setup()`` to setup test environment.
* Linux platform discovery will no longer use ``platform.linux_distribution()``
on Python >=3.6.6. due to pending deprecation warning.
* Updated Linux Guide as Xonsh is now available in Arch Linux official repositories.
**Fixed:**
* Builtin dynamic proxies and deprecation warning proxies were not deleting
attributes and items properly.
* Fixed stdout/sdterr writing infinite recurssion error that would occur in
long pipelines of callable aliases.
* Fixed a bug which under very rare conditions could cause the shell
to die with PermissionError exception while sending SIGSTOP signal
to a child process.
* Fixed further raw string deprecation warnings thoughout the code base.
v0.8.0
====================
**Added:**
* Windows CI jobs on Azure Pipelines
* The ``cryptop`` command will no longer have its output captured
by default.
* Added new env-var ``PTK_STYLE_OVERRIDES``. The variable is
a dictionary containing custom prompt_toolkit style definitions.
For instance::
$PTK_STYLE_OVERRIDES['completion-menu'] = 'bg:#333333 #EEEEEE'
will provide for more visually pleasing completion menu style whereas::
$PTK_STYLE_OVERRIDES['bottom-toolbar'] = 'noreverse'
will prevent prompt_toolkit from inverting the bottom toolbar colors
(useful for powerline extension users)
Note: This only works with prompt_toolkit 2 prompter.
**Changed:**
* All ``__xonsh_*__`` builtins have been migrated to a ``XonshSession`` instance at
``__xonsh__``. E.g. ``__xonsh_env__`` is now ``__xonsh__.env``.
* Other xonsh-specific builtins (such as ``XonshError``) have been proxied to
the ``__xonsh__`` session object as well.
**Deprecated:**
* All ``__xonsh_*__`` builtins are deprected. Instead, the corresponding
``__xonsh__.*`` accessor should be used. The existing ``__xonsh_*__`` accessors
still work, but issue annoying warnings.
**Fixed:**
* Fixed deprecation warnings from unallowed escape sequences as well as importing abstract base classes directly from ``collections``
* Fix for string index error in stripped prefix
* bash_completions to include special characters in lprefix
Previously, glob expansion characters would not be included in lprefix for replacement
.. code-block:: sh
$ touch /tmp/abc
$ python
>>> from bash_completion import bash_completions
>>>
>>> def get_completions(line):
... split = line.split()
... if len(split) > 1 and not line.endswith(' '):
... prefix = split[-1]
... begidx = len(line.rsplit(prefix)[0])
... else:
... prefix = ''
... begidx = len(line)
... endidx = len(line)
... return bash_completions(prefix, line, begidx, endidx)
...
>>> get_completions('ls /tmp/a*')
({'/tmp/abc '}, 0)
Now, lprefix begins at the first special character:
.. code-block:: sh
$ python
>>> from bash_completion import bash_completions
>>>
>>> def get_completions(line):
... split = line.split()
... if len(split) > 1 and not line.endswith(' '):
... prefix = split[-1]
... begidx = len(line.rsplit(prefix)[0])
... else:
... prefix = ''
... begidx = len(line)
... endidx = len(line)
... return bash_completions(prefix, line, begidx, endidx)
...
>>> get_completions('ls /tmp/a*')
({'/tmp/abc '}, 7)
* The ``xonsh.main.setup()`` function now correctly passes the
``shell_type`` argument to the shell instance.
* try_subproc_toks now works for subprocs with trailing and leading whitespace
Previously, non-greedy wrapping of commands would fail if they had leading and trailing whitespace:
.. code-block:: sh
$ true && false || echo a
xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True
NameError: name 'false' is not defined
$ echo; echo && echo a
xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True
NameError: name 'echo' is not defined
Now, the commands are parsed as expected:
.. code-block:: sh
$ true && false || echo a
a
$ echo; echo && echo a
a
v0.7.10
====================
**Added:**
* 'off' can be passed as falsy value to all flags accepting boolean argument.
- DragonFly BSD support
* Format strings (f-strings) now allow environment variables to be looked up.
For example, ``f"{$HOME}"`` will yield ``"/home/user"``. Note that this will
look up and fill in the ``detype()``-ed version of the environment variable,
i.e. it's native string representation.
**Changed:**
* Running ``aurman`` command will now be predicted to be unthreaded by default.
**Fixed:**
* The xonsh ``xonfig wizard`` would crash if an unknown foreign shell was
provided. This has been fixed.
* The ``hg split`` command will now predict as unthreadable.
* Fixed path completer crash on attempted f-string completion
v0.7.9
====================
**Added:**
* The python-mode ``@(expr)`` syntax may now be used inside of subprocess
arguments, not just as a stand-alone argument. For example:
.. code-block:: sh
$ x = 'hello'
$ echo /path/to/@(x)
/path/to/hello
This syntax will even properly expand to the outer product if the ``expr``
is a list (or other non-string iterable) of values:
.. code-block:: sh
$ echo /path/to/@(['hello', 'world'])
/path/to/hello /path/to/world
$ echo @(['a', 'b']):@('x', 'y')
a:x a:y b:x b:y
Previously this was not possible.
* New ``$DOTGLOB`` environment variable enables globs to match
"hidden" files which start with a literal ``.``. Set this
variable to ``True`` to get this matching behavior.
Cooresponding API changes have been made to
``xonsh.tools.globpath()`` and ``xonsh.tools.iglobpath()``
* New environment variable ``$FOREIGN_ALIASES_SUPPRESS_SKIP_MESSAGE``
enables the removal of skipping foreign alias messages.
* New ``--suppress-skip-message`` command line option for skipping
foreign alias messages when sourcing foreign shells.
**Fixed:**
* In Bash completions, if there are no files to source, a ``set()`` will
no longer be inserted into the completion script.
* Fixed issue with TAB completion in readline not replacing values
with spaces properly when the prefix was unquoted.
v0.7.8
====================
**Added:**
* ``xonsh.lib.collections.ChainDB``, a chain map which merges mergable fields
**Fixed:**
* Pass all params to voxapi.create
* PTK tab-completion now auto-accepts completion if only one option is present
(note that fix is only for PTK2)
v0.7.7
====================
**Added:**
* A xontrib which adds support for autojump to xonsh
* Added new env-var ``XONSH_HISTORY_MATCH_ANYWHERE``. If set to ``True`` then
up-arrow history matching will match existing history entries with the search
term located anywhere, not just at the beginning of the line. Default value is
``False``
**Changed:**
* Improved iteration over virtual environments in ``Vox.__iter__``
**Fixed:**
* Fix for ``Enter`` not returning from Control-R search buffer
* Fixed automatic wrapping of many subprocesses that spanned multiple lines via
line continuation characters with logical operators separating the commands.
For example, the following now works:
.. code-block:: sh
echo 'a' \
and echo 'b'
* Environment swapping would not properly reraise errors due to weird
Python name binding issue.
v0.7.6
====================
**Added:**
* Callable aliases may now accept a ``stack`` argument. If they do, then the
stack, as computed from the aliases call site, is provided as a list of
``FrameInfo`` objects (as detailed in the standard library ``inspect``
module). Otherwise, the ``stack`` parameter is ``None``.
* ``SubprocSpec`` now has a ``stack`` attribute, for passing the call stack
to callable aliases. This defaults to ``None`` if the spec does not
need the stack. The ``resolve_stack()`` method computes the ``stack``
attribute.
**Changed:**
* xonsh/environ.py
Exceptions are caught in the code executed under Env.swap()
**Fixed:**
* Scripts are now cached by their realpath, not just abspath.
* Fixed a potential crash (``AssertionError: wrong color format``) on Python 3.5 and prompt_toolkit 1.
* The ``completer`` command now correctly finds completion functions
when nested inside of other functions.
* Fixed a crash when using the ``$XONSH_STDERR_PREFIX/POSTFIX`` with
prompt_toolkit and Pygments 2.2.
v0.7.5
====================
**Fixed:**
* Recent command history in ptk2 prompt now returns most recently executed
commands first (as expected)
* Fixed a regression taat prevented the readline backend from beeing used. This
regression was caused by the new ansi-color names, which are incompatible with
pygments 2.2.
v0.7.4
====================
**Added:**
* New ``xonsh-cat`` command line utility, which is a xonsh replacement
for the standard UNIX ``cat`` command.
* The new ``xonsh.xoreutils.cat.cat_main()`` enables the ``xonsh.xoreutils.cat``
module to be run as a command line utility.
* New ``CommandsCache.is_only_functional_alias()`` and
``CommandsCache.lazy_is_only_functional_alias()`` methods for determining if
if a command name is only implemented as a function, and thus has no
underlying binary command to execute.
* ``xonsh.xontribs.xontribs_load()`` is a new first-class API for loading
xontribs via a Python function.
* ``$COMPLETIONS_DISPLAY`` now supports readline-like behavior on
prompt-toolkit v2.
**Changed:**
* The xonsh Jupyter kernel now will properly redirect the output of commands
such as ``git log``, ``man``, ``less`` and other paged commands to the client.
This is done by setting ``$PAGER = 'cat'``. If ``cat`` is not available
on the system, ``xonsh-cat`` is used instead.
* The ``setup()`` function for starting up a working xonsh has ``aliases``,
``xontribs``, and ``threadable_predictors`` as new additional keyword
arguments for customizing the loading of xonsh.
**Fixed:**
* Fixed a bug with converting new PTK2 colors names to old names when using PTK1 or Jupyter
as the shell type.
* ``CommandsCache.locate_binary()`` will now properly return None when
``ignore_alias=False`` and the command is only a functional alias,
such as with ``cd``. Previously, it would return the name of the
command.
* Fixed issue with ``$COMPLETIONS_DISPLAY`` raising an error on
prompt-toolkit v2 when the value was not set to ``multi``.
* ValueError when executing ``vox list``
v0.7.3
====================
**Added:**
* Add the ``PROMPT_TOOLKIT_COLOR_DEPTH`` environment to xonsh default environment.
Possible values are ``DEPTH_1_BIT``/``MONOCHROME``,
``DEPTH_4_BIT``/``ANSI_COLORS_ONLY``, ``DEPTH_8_BIT``/``DEFAULT``, or ``DEPTH_24_BIT``/``TRUE_COLOR``.
Note: not all terminals support all color depths.
* New way to fix unreadable default terminal colors on Windows 10. Windows 10
now supports true color in the terminal, so if prompt toolkit 2 is
installed Xonsh will use a style with hard coded colors instead of the
default terminal colors. This will give the same color experience as on linux an mac.
The behaviour can be disabled with ``$INTENSIFY_COLORS_ON_WIN``
environment variable.
* New ``JupyterShell`` for interactive interfacing with Jupyter.
**Changed:**
* All ansicolor names used in styles have ben updated to the color names used by prompt_toolkit 2.
The new names are are much easier to understand
(e.g. ``ansicyan``/``ansibrightcyan`` vs. the old ``#ansiteal``/``#ansiturquoise``). The names are automatically
translated back when using prompt_toolkit 1.
**Removed:**
* Removed support for pygments < 2.2.
**Fixed:**
* New ansi-color names fixes the problem with darker colors using prompt_toolkit 2 on windows.
* Fixed a problem with the color styles on prompt toolkit 2. The default pygment
style is no longer merged into style selected in xonsh.
* The JupyterKernel has been fixed from a rather broken state.
v0.7.2
====================
**Added:**
* ``history show`` builtin now supports optional ``-0`` parameter that switches
the output to null-delimited. Useful for piping history to external filters.
**Fixed:**
* If exception is raised in indir context manager, return to original directory
* Fixed issue that autocomplete menu does not display
at terminal's maximum height
v0.7.1
====================
**Added:**
* Added feature to aliases.
* ``xonsh.lib.os.rmtree()`` an rmtree which works on windows properly (even with
git)
**Changed:**
* set default value of ``$AUTO_SUGGEST_IN_COMPLETIONS=False``
* Use the ``pygments_cache.get_all_styles()`` function instead of
interacting directly with pygments.
**Fixed:**
* Fixed issue with ``$ARG<N>`` varaibles not being passed to subprocesses correctly.
* Fixed issue with multiline string inside of ``@(expr)`` in
unwrapped subprocesses. For example, the following now works::
echo @("""hello
mom""")
* ``CommandPipeline.output`` now does properly lazy, non-blocking creation of
output string. ``CommandPipeline.out`` remains blocking.
* Fix regression in ``INTENSIFY_COLORS_ON_WIN`` functionality due to prompt_toolkit 2 update.
* Fixed issue that can't insert quotation marks and double quotes
for completion.
* Fixed issue with ``SyntaxErrors`` being reported on the wrong line
when a block of code contained multiple implicit subprocesses.
* ``prompt_toolkit >= 2`` will start up even if Pygments isn't present
* Fixed a regression with ``xonfig styles`` reporting ``AttributeError: module 'pygments' has no attribute 'styles'``
* ptk dependent xontribs (that use custom keybindings) now work with both ptk1
and ptk2
* Fixed async tokenizing issue on Python v3.7.
v0.7.0
====================
**Added:**
* Added a hook for printing a spcial display method on an object.
* Support for ``prompt_toolkit 2.0``
* The ``--shell-type`` (``$SHELL_TYPE``) may now be specified using
shortcuts, such as ``rl`` for ``readline`` and ``ptk2`` for
``prompt_toolkit2``. See ``xonsh --help`` for a full listing
of available aliases.
**Fixed:**
- Restored AUGASSIGN_OPS definition, which was inadvertently removed.
v0.6.10
====================
**Added:**
* ``xonsh.lib.subprocess.check_output`` as a ``check_output`` drop in
**Fixed:**
* ``xonsh.lib.subprocess.run`` doesn't change dirs unless asked
v0.6.9
====================
**Added:**
* New xonsh standard library ``xonsh.lib`` subpackage
* ``xonsh.lib.os.indir`` a context manager for temporarily entering into a directory
* ``xonsh.lib.subprocess.run`` and ``xonsh.lib.subprocess.check_call``
subprocess stubs using ``xonsh`` as the backend
**Fixed:**
* update xoreutils._which.which() for python 3.x support.
* Fixed issue with incorrect strip lengths for prefixes with quotes in them
* Fixed bash script to also consider leading double quotes and not just single
quotes
* Launching xonsh with prompt_toolkit version 2.x no longer fails, and instead fallsback to readline shell. This is a patch for until prompt_toolkit 2.x support is fully implemented. See PR #2570
v0.6.8
====================
**Fixed:**
* completions relative to ``CDPATH`` only trigger when used with ``cd``
* Import of ``ctypes.util`` is now explictly performed, as needed.
Python v3.7 no longer imports this module along with ``ctypes``.
* Fixed issue with pygments-cache not properly generating a cache the first
time when using prompt-toolkit. This was due to a lingering lazy import
of ``pkg_resources`` that has been removed.
* Removed duplicate ``pip`` completer
* ``bash_completion`` no longer returns invalid prefix lengths for directories
containing escape file names
* Fixed error when using redirection (e.g., >) on Windows.
v0.6.7
====================
**Changed:**
* Xonsh live example has been re-added back to the documentation.
**Fixed:**
* Fixed issue where xonsh would fail to properly return the terminal prompt
(and eat up 100% CPU) after a failed subprocess command in interactive mode
if ``$RAISE_SUBPROC_ERROR = True``.
* ``xonsh.tokenize.tok_name`` no longer mutates the standard library ``tokenize.tok_name``.
A copy is made on import instead.
v0.6.6
====================
**Added:**
* A multipurpose add method to EnvPath. For example:
.. code-block:: xonshcon
$ $PATH
EnvPath(
['/usr/bin', '/usr/local/bin', '/bin']
)
$ $PATH.add('~/.local/bin', front=True); $PATH
EnvPath(
['/home/user/.local/bin', '/usr/bin', '/usr/local/bin', '/bin']
)
$ $PATH.add('/usr/bin', front=True, replace=True); $PATH
EnvPath(
['/usr/bin', '/home/user/.local/bin', '/usr/local/bin', '/bin']
)
* Added ``pygments-cache`` project in order to reduce startup time.
**Changed:**
* built_ins.py, corrected a typo.
* test/test_news.py
It now uses regex to verify the format of rst files
* Mercurial (``hg``) will no longer run in a threadable subprocess when
it is run in interactive mode.
**Fixed:**
* issue 2313
v0.6.5
====================
**Added:**
* Wizard ``FileInsterter`` node class now has ``dumps()`` method for
converting a mapping to a string to insert in a file.
**Fixed:**
* Fixed issue with ``xonfig wizard`` writer failing to write valid run control
files for environment variables that are containter types. In particular,
the storage of ``$XONSH_HISTORY_SIZE`` has been fixed.
v0.6.4
====================
**Changed:**
* Error message improved for sourcing foreign shells, when file cannot be found
or there is a syntax error.
**Fixed:**
* Fixed issues with readline completer tab completing entries
with spaces.
* Fixed ``xonsh.tools.columnize()`` bug the prevented single-row
input from being columnized correctly.
* Now honor ASYNC and AWAIT as keywords in tokenizer on
Python 3.7.
v0.6.3
====================
**Added:**
* Docs for using ``@(<expr>)`` as a way to run commands and a gotcha about
list of strings vs single string expressions.
* Ubuntu versions which xonsh is packaged for (with xonsh versions)
**Changed:**
* When reporting errors without a traceback (i.e. ``$XONSH_SHOW_TRACEBACK = False``) and the error is a ``XonshError``
the exception type is not longer printed.
* ``CommandPipeline.proc`` may now be ``None``, to accomodate when the process
fails to even start (i.e. a missing command or incorrect permisions).
**Fixed:**
* The ``curl`` command will now be run in a thread, which prevents documents that
do not end in a newline from writing over the next prompt and vice versa.
* Fix bug on Windows when ``PATHEXT`` environment variable did not exist.
This also fixes building the xonsh documentation on Windows.
* Fixed a bug in the `free_cwd <http://xon.sh/xontribs.html#free-cwd>`__ Windows Xontrib, which caused the prompt to error if the current directory is
deleted/renamed from an other process.
* Fixed issue with ``$XONSH_SHOW_TRACEBACK`` not being respected in subprocess
mode when the command could not be found or had incorrect permissions.
v0.6.2
====================
**Added:**
* Release tarballs now include licenses and minimal documentation for xonsh and ply
* Wizard now has a ``FileInserter`` node that allows blocks to be
inserted and replaced inside of a file. This adheres to conversion
rules fordumping as provided on this node.
* New ``xonsh.wizard.StateVisitor.flatten()`` method for flattening the
current state.
**Changed:**
* The xonsh startup wizard will only be triggered if no xonshrc files exist
and the file ``~/.local/config/xonsh/no-wizard`` is not present.
* The ``xonfig wizard`` command will now run write out to the xonshrc file.
* Wizard nodes ``Save`` and ``Load`` had their names changed to ``SaveJSON``
and ``LoadJSON``.
**Removed:**
* Static configuration is dead (``config.json``), long live run control (``xonshrc``)!
* The following evironment variables have been removed as they are no longer needed:
``$LOADED_CONFIG`` and ``$XONSHCONFIG``.
* Many support functions for static configuration have also been removed.
**Fixed:**
* Files starting with ``#`` are auto-escaped by TAB completion
v0.6.1
====================
**Added:**
* Support for MSYS2.
* New ``xonsh.main.setup()`` function for starting up xonsh in 3rd party
packages.
**Changed:**
* Updated CircleCI to use circle version 2.0
* Replaced StopIteration with return in CommandPipeline.iterraw.
* Xonsh run control now also looks for the XDG-compliant file
``~/.config/xonsh/rc.xsh`` at startup.
**Fixed:**
* Clean out ``$LINES`` and ``$COLUMNS`` if set, preventing some programs from drawing weirdly
* cat from xoreutils now outputs in configured encoding
* Fixed hanging issue with pipelines whose middle processes exit before the
first or last process.
* Fixed issue where xonsh would deduplicate spaces from bash autocompletions.
* Fixed failing redirections from stderr to stdout when the command
being executed was a callable alias.
* Ensure that the ``free_cwd`` contrib can only be active on pure Windows.
* Made an exceptional case in ``iglobpath()`` more robust when Python globbing
fails for due to strange scrandir issue.
* Unexpected process suspension on Cygwin and MSYS2.
* ``$XONSH_APPEND_NEWLINE`` will now default to True when in interactive mode.
* Fixed issue with uncalled lambdas being run in subproc mode.
* Lambda nodes not have proper line and column numbers in AST.
* Properly throw ``SyntaxError`` when no kwargs are defined
in a kwarg-only function. This used to throw a
``TypeError: 'NoneType' object is not iterable``.
* Addressed issue where encoding and errors were None when teeing output.
* Commands like ``git c`` would complete to ``git 'checkout '`` because git adds an extra space
to the end of the completion, which was being captured in the completion. Xonsh now fixes the git issue
while retaining all whitespace when there is other internal whitespace.
v0.6.0
====================
**Added:**
* Added an alias command, matching bash's implementation, available as part of bashisms.
* New ``$AUTO_SUGGEST_IN_COMPLETIONS`` environment variable that enables/disables
whether the auto-suggestion result appears in the tab completions.
* Added ``__add__()`` and ``__radd__()`` methods to ``EnvPath``.
* Xonsh now supports f-strings, as in Python v3.6+.
* Added ``ipython`` as unthreadable in command cache threadabilty predictors.
* Added ``whole_word_jumping`` xontrib
* Added ``$XONSH_APPEND_NEWLINE`` environment variable
* Support for PEP 515: Underscores in Numeric Literals
* ``xonsh.color_tools.make_palette()``
Simple rename of the pre-existing
``xonsh.color_tools.make_pallete()`` function.
* ``xonsh.tools.decorator()`` function/method decorator.
This allows for an API function to be annotated with a
decorator that documents deprecation, while also tying in
functionality that will warn a user that the function has
been deprecated, and, raise an ``AssertionError`` if the
function has passed its expiry date.
* New xontrib ``schedule`` (Xonsh Task Scheduler)
**Changed:**
* ``on_pre_prompt`` is now fired before prompt calculations are made, allowing modifications to the prompt.
* ``emacsclient`` will now return false in the threadable predictors.
* Improved the autopair behavior to match that of popular code editors.
* Moved the lazy ``pkg_resources`` package back to its original
place. The will hopefully address some of the slowdown issues
experiances on some platforms.
* When xonsh is used to run an ``xsh`` script, the ``xonshrc`` is not loaded
* Change in the behavior of the default predictor with binary analysis. The pattern ``libgpm`` is use, assuming when ``gpm`` is used the program is not threadable. This change solves issues with programs as ``links``.
* Error messages added to the ``source`` command if it is used with a language
that is not xonsh or Python.
**Deprecated:**
* ``xonsh.color_tools.make_pallette()``
Deprecated in release 0.5.10 and will be removed in release 0.6.0.
**Fixed:**
* Now f-strings can be used inside @() without explicit enclosing command in ![]
* Fix for ``x, y, *z = ...`` unpacking.
* Git branch detection now correctly passes the environment down to the subprocess
call. This allows for branch detection when git is installed into a non-standard
location.
* Escape regex characters in ``path_complete`` to avoid regex parsing errors for
certain combinations of characters in path completer
* gistatus: Fixed hash not being shown when in detaced HEAD and there are no tags
* Fix branch colorization when ``git`` or ``hg`` are aliases.
* Fixed leftover ``.git/index.lock`` in ``gitstatus``
* Made JSON history loading more robust to corrupt files.
* Starting a new command with an open parentheses will no longer
throw a traceback when ``$UPDATE_COMPLETIONS_ON_KEYPRESS`` is
``True``.
* Automatically wrapping subprocess calls would sometimes include
semincolons and other line-ending tokens, rather than stopping at them.
This has been fixed.
* Numerous spelling errors in documentation, docstrings/comments, text
strings and local variable names.
* Spelling error in the ``xonsh.color_tools.make_pallete()`` public
function declaration. This was fixed by renaming the function to
``xonsh.color_tools.make_palette()`` while maintaining a binding
of ``make_pallete()`` to the new ``make_palette()`` in case users
are already used to this API.
* Fixed issue with starting triple quote strings being run as a command.
* Fixed a problem with escaping charet (^) character for cmd.exe in the source-cmd function.
* ``EOF in multi-line statement`` errors were misreported as being on line 0.
Now they are correctly reported as being on the last line of the file.
v0.5.12
====================
**Fixed:**
* Fixed ``release.xsh`` to prevent it from dirtying the repo on release and
leading to an unwanted ``.dev`` suffix on the version number
v0.5.11
====================
**Added:**
* ``release.xsh`` creates a github release with the merged news entries as the
release body
**Fixed:**
* ``xonfig`` now displays the proper value for "on linux"
v0.5.10
====================
**Added:**
* Added ``xclip`` and ``repo`` to default threadable predictors (Issues #2355
and #2348)
* Pretty printing of the $PATH variable
* Add "fzf-widgets" xontrib which provides fuzzy search productivity widgets
with on custom keybindings to xontrib list.
* New ``free_cwd`` xontrib for Windows, which prevent the current directory from being locked when the prompt is shown.
This allows the other programs or Windows explorer to delete the current or parent directory. This is accomplished by
resetting the CWD to the users home directory temporarily while the prompt is displayed. The directory is still locked
while any commands are processed so xonsh still can't remove it own working directory.
**Changed:**
* Codecov threshold to 2%
**Removed:**
* On Windows environments variables in wrapped like``%foo%`` are no longer expanded automatically.
**Fixed:**
* Fixed the ``--rc`` option so it now runs xonsh with the specified rc file
* ``@$`` operator now functions properly when returned command is an alias
* Correct line continuation would not work on Windows if the line continuations were used
in the ``xonshrc`` file.
* Fixed a regression in the Windows ``sudo`` command, that allows users to run elevated commands in xonsh.
* Fix echo command from xoreutils.
* Fixed a bug on Windows which meant xonsh wasn't using PATH environment variable but instead relying on a default
value from the windows registry.
v0.5.9
====================
**Added:**
* Add ``Alt .`` keybinding to ``bashisms-xontrib`` to insert last argument of
previous command into current buffer
**Fixed:**
* Fix crash when openSSH version of bash is on PATH on Windows.
* Added missing ensurers to make sure that ``bool`` env_vars are bools and
``int`` env_vars are integers:
* ``DIRSTACK_SIZE``
* ``EXPAND_ENV_VARS``
* ``PUSHD_MINUS``
* ``PUSHD_SILENT``
* ``SUGGEST_COMMANDS``
* ``SUGGEST_MAX_NUM``
* ``SUGGEST_THRESHOLD``
v0.5.8
====================
**Changed:**
* The ``xonsh.platform.os_environ`` wrapper is now case-insensitive and
case-preserving on Windows.
* The private ``_TeeStd`` class will no longer attempt to write to a
standard buffer after the tee has been 'closed' and the standard
buffer returned to the system.
**Fixed:**
* Fixed a bug on py34 where os.scandir was used by accident.
* Line continuations (``\\``) is subproc mode will no longer consume the
surrounding whitespace.
* Fixed a bug if foreign_shell name was not written in lower case in
the static configuration file ``config.json``
* Fixed a regression on Windows where caused ``which`` reported that the
``PATH`` environment variable could not be found.
* Fixed issue with foregrounding jobs that were started in the background.
* Fixed that ``Ctrl-C`` crashes xonsh after running an invalid command.
* Fixed an potential ``ProcessLookupError`` issue, see #2288.
v0.5.7
====================
**Added:**
* New ``color_tools`` module provides basic color tools for converting
to and from various formats as well as creating palettes from color
strings.
* Redirections may now be used in string and list-of-strings
aliases.
* Subprocess redirection may now forego the whitespace between the
redirection and a file name. For example,
``echo hello world >/dev/null``.
* Add a ``-P`` flag to the ``cd`` function in order to change directory and
following symlinks.
* ``xonfig tutorial`` command to launch the http://xon.sh/tutorial in the
browser.
* ``@(...)`` syntax now supports generators and tuples without parentheses.
* Sourcing foreign shells now have the ``--show`` option, which
lets you see when script will be run, and the ``--dryrun``
option which prevents the source from actually taking place.
Xonsh's foreign shell API also added these keyword arguments.
* Subprocess mode now supports subshells. Place any xonsh
code between two parentheses, e.g. ``(cmd)``, to run
this command in a separate xonsh subprocess.
* Foreign shell aliases now have the ability to take extra arguments,
if needed.
* Xonsh will issue a warning message when the current working
directory has been remove out from under it and not replaced
prior to running the next command.
* Line continuation backslashes are respected on Windows in the PTK shell if
the backspace is is preceded by a space.
* Added ``ponysay`` as a command which will usually not run in a
threaded mode in the commands cache.
* New ``jsonutils`` module available for serializing special
xonsh objects to JSON.
**Changed:**
* The literal tokens ``and`` and ``or`` must be surrounded by
whitespace to delimit subprocess mode. If they do not have
whitespace on both sides in subproc mode, they are considered
to be part of a command argument.
* The ``xontrib`` command is now flagged as unthreadable and will be
run on the main Python thread. This allows xontribs to set signal
handlers and other operations that require the main thread.
* nvim (Neovim) has been flagged as unthreadable
* The interactive prompt will now catch ``SystemExit`` and, instead
of exiting the session, will refresh the prompt. This is the same
process as for keyboard interrupts.
* Xonsh no longer launches the wizard for new users. Instead a welcome screen is
shown which says how to launch the wizard.
* Added Windows ``expanduser()``-like function which prevents
the expansion of ``~`` that are not followed by a path
separator.
* Collecting xonsh history files was reported to have random runtime
OSError failures. This exception is now handled, just in case. The
The exception will still be printed in debug mode.
* ``Shell.stype`` has been renamed to ``Shell.shell_type``.
* The configuration wizard now displays the proper control sequence to leave
the wizard at the to start of the wizard itself. Note that this is Ctrl+D for
readline and Ctrl+C for prompt-toolkit.
* Callable alias proxy functions are now more friendly to
``functools.partial()``.
* ``prompt.vc.get_hg_branch`` now uses ``os.scandir`` to walk up the filetree
looking for a ``.hg`` directory. This results in (generally) faster branch
resolution compared to the subprocess call to ``hg root``.
* Xonsh's script and code caches will are now invalidated whenever the
xonsh version changes for a given Python version.
* Autowrapping of subprocess globs has been improved to cover
more cases that are ambiguous with Python syntax.
* Job control info when foregrounding or backgrounding jobs will now
only be displayed when xonsh is in interactive mode.
* Enabled virtual terminal processing in the prompt-toolkit shell for Windows.
**Fixed:**
* 3rd party pygments styles (like solorized or monokailight) are now
able to be used in xonsh. These styles are dynamically created upon
first use, rather than being lazily loaded by xonsh.
* On Windows, ``os.environ`` is case insensitive. This would potentially
change the case of environment variables set into the environment.
Xonsh now uses ``nt.environ``, the case sensitive counterpart, to avoid
these issues on Windows.
* Fix how ``$PWD`` is managed in order to work with symlinks gracefully
* ``history replay`` no longer barfs on ``style_name`` when setting up the
environment
* ``Shell.shell_type`` is now properly set to the same value as ``$SHELL_TYPE``.
* Fixed ``source-zsh`` to work with zsh v5.2.
* Fixed issue where ``del (x, y)`` would raise a syntax error.
* Certain vim commands issue commands involving subshells,
and this is now supported.
* Null bytes handed to Popen are now automatically escaped prior
to running a subprocess. This prevents Popen from issuing
embedded null byte exceptions.
* Xonsh will no longer crash is the current working directory is
removed out from under it.
* Multiline strings can now be written in subprocess mode.
* PTK completions will now correctly deduplicate autosuggest completions
and display completions values based on the cursor position.
* Fixed bug where trailing backspaces on Windows paths could be interpreted
as line continuations characters. Now line continuation characters must be
preceded by a space on Windows. This only applies to xonsh in interactive
mode to ensure scripts are portable.
* Importing ``*.xsh`` files will now respect the encoding listed in
that file and properly fallback to UTF-8. This behaviour follows
the rules described in PEP 263.
* Wizard is now able to properly serialize environment paths.
v0.5.6
====================
**Added:**
* New core utility function aliases (written in pure Python) are now
available in ``xonsh.xoreutils``. These include: ``cat``, ``echo``,
``pwd``, ``tee``, ``tty``, and ``yes``. These are not enabled by default.
Use the new ``coreutils`` xontrib to load them.
* CircleCI test post codecov run
* The ``trace`` will automatically disable color printing when
stdout is not a TTY or stdout is captured.
* New ``jedi`` xontrib enables jedi-based tab completions when it is loaded.
This supersedes xonsh's default Python-mode completer.
* The lexer has a new ``split()`` method which splits strings
according to xonsh's rules for whitespace and quotes.
* New events for hooking into the Python import process are now available.
You can now provide a handler for:
- ``on_import_pre_find_spec``
- ``on_import_post_find_spec``
- ``on_import_pre_create_module``
- ``on_import_post_create_module``
- ``on_import_pre_exec_module``
- ``on_import_post_exec_module``
**Changed:**
* The prompt toolkit shell's first completion will now be the
current token from the auto-suggestion, if available.
* Sourcing foreign shells will now safely skip applying aliases
with the same name as existing xonsh aliases by default.
This prevents accidentally overwriting important xonsh standard
aliases, such as ``cd``.
**Fixed:**
* Threadable prediction for subprocesses will now consult both the command
as it was typed in and any resolved aliases.
* The first prompt will no longer print in the middle of the line if the user has
already started typing.
* Windows consoles will now automatically enable virtual terminal processing
with the readline shell, if available. This allows the full use of ANSI
escape sequences.
* On the Windows readline shell, the tab-completion suppression prompt will no
longer error out depending on what you press.
* Fixed issue with subprocess mode wrapping not respecting line continuation
backslashes.
* Handle a bug where Bash On Windows causes platform.windows_bash_command()
to raise CalledProcessError.
* Fixed issues pertaining to completing from raw string paths.
This is particularly relevant to Windows, where raw strings
are inserted in path completion.
* Replace deprecated calls to ``time.clock()`` by calls to
``time.perf_counter()``.
* Use ``clock()`` to set the start time of ``_timings`` in non-windows instead
of manually setting it to ``0.0``.
* The ``trace`` utility will now correctly color output and not
print extraneous newlines when called in a script.
* The ``@$(cmd)`` operator now correctly splits strings according to
xonsh semantics, rather than just on whitespace using ``str.split()``.
* The ``mpl`` xontrib has been updated to improve matplotlib
handling. If ``xontrib load mpl`` is run before matplotlib
is imported and xonsh is in interactive mode, matplotlib
will automatically enter interactive mode as well. Additionally,
``pyplot.show()`` is patched in interactive mode to be non-blocking.
If a non-blocking show fails to draw the figure for some reason,
a regular blocking version is called.
* Fixed issues like ``timeit ls`` causing OSError - "Inappropriate ioctl
for device".
* Fixed a potential "OSError: [Errno 22] Invalid argument" to increase job
control stability.
v0.5.5
====================
**Added:**
* New ``--rc`` command line option allows users to specify paths to run control
files from the command line. This includes both xonsh-based and JSON-based
configuration.
* New ``$UPDATE_COMPLETIONS_ON_KEYPRESS`` controls whether or not completions
will automatically display and update while typing. This feature is only
available in the prompt-toolkit shell.
**Changed:**
* Xonsh scripts now report ``__file__`` and ``__name__`` when run as scripts
or sourced. These variables have the same meaning as they do in Python
scripts.
* ``$XONSHRC`` and related configuration variables now accept JSON-based
static configuration file names as elements. This unifies the two methods
of run control to a single entry point and loading system.
* The ``xonsh.shell.Shell()`` class now requires that an Execer instance
be explicitly provided to its init method. This class is no longer
responsible for creating an execer an its dependencies.
* Moved decorators ``unthreadable``, ``uncapturable`` from
``xonsh.proc`` to ``xonsh.tools``.
* Some refactorings on jobs control.
**Deprecated:**
* The ``--config-path`` command line option is now deprecated in favor of
``--rc``.
**Removed:**
* ``xonsh.environ.DEFAULT_XONSHRC`` has been removed due to deprecation.
For this value, please check the environment instead, or call
``xonsh.environ.default_xonshrc(env)``.
**Fixed:**
* Command pipelines that end in a callable alias are now interruptable with
``^C`` and the processes that are piped into the alias have their file handles
closed. This should ensure that the entire pipeline is closed.
* Fixed issue where unthreadable subprocs were not allowed to be
captured with the ``$(cmd)`` operator.
* The ``ProcProxy`` class (unthreadable aliases) was not being executed and would
hang if the alias was capturable. This has been fixed.
* Fixed a ``tcsetattr: Interrupted system call`` issue when run xonsh scripts.
* Fixed issue with ``ValueError`` being thrown from ``inspect.signature()``
when called on C-extension callables in tab completer.
* Fixed issue that ``ls | less`` crashes on Mac.
* Threadable prediction was incorrectly based on the user input command, rather than
the version where aliases have been resolved. This has been corrected.
v0.5.4
====================
**Added:**
* Add alias ``xip`` ("kip") so that xonsh's Python environment (whatever that is) can be modified.
* HistoryEntry, a SimpleNamespace object that represents a command in history.
* ``xonsh.completers.bash_completion`` module
* Added option to report timing information of xonsh startup times. Start xonsh
with the ``--timings`` flag to use the feature.
* The Python tab completer will now complete the argument names of functions
and other callables.
* Uptime module added to ``xonsh.xoreutils``. This can report the system
boot time and up time.
* The environment variable ``XONSH_HISTORY_BACKEND`` now also supports a
value of class type or a History Backend instance.
* ``on_envvar_new`` event that fires after a new envvar is created.
* ``on_envvar_change`` event that fires after an envvar is changed.
**Changed:**
* history indexing api to be more simple, now returns HistoryEntry.
* Decoupled ``bash_completion`` from xonsh project and added shim back to
xonsh.
* The JSON history backend will now unlock history files that were created
prior to the last reboot.
**Fixed:**
* Fixed broken bash completions on Windows if 'Windows Subsystem for Linux' is installed.
* Readline history would try to read the first element of history prior to
actually loading any history. This caused an exception to be raised on
Windows at xonsh startup when using pyreadline.
* Fixed issue with readline tab completer overwriting initial prefix in
some instances.
* Fixed issue wherein if ``git`` or (presumably) ``hg`` are aliased, then branch
information no longer appears in the ``$PROMPT``
* Fixed an issue with commands that background themselves (such as
``gpg-connect-agent``) not being able to be run from within xonshrc.
v0.5.3
====================
**Added:**
* Tab completion xontrib for python applications based on click framework.
* Added ``on_transform_command`` event for pre-processing that macros can't handle.
* Autodetection of backgroundability by binary analysis on POSIX.
* New argument ``expand_user=True`` to ``tools.expand_path``.
* New ``$COMPLETION_QUERY_LIMIT`` environment variable for setting the
number of completions above which the user will be asked if they wish to
see the potential completions.
* Users may now redirect stdout to stderr in subprocess mode.
**Changed:**
* The ``Block`` and ``Functor`` context managers from ``xonsh.contexts`` have been
rewritten to use xonsh's macro capabilities. You must now enter these via the
``with!`` statement, e.g. ``with! Block(): pass``.
* The ``distributed`` xontrib now needs to use the ``with!`` statement, since it
relies on ``Functor``.
* ``telnet`` has been flagged as unthreadable.
* When ``$DYNAMIC_CWD_ELISION_CHAR`` is non empty and the last dir of cwd is too
long and shortened, the elision char is added at the end.
* ``pygments`` is no longer a strict dependency of the ``prompt_toolkit``
backend. If ``pygments`` is not installed, the PTK backend will use the
default ansi color settings from the terminal. Syntax highlighting requires
that ``pygments`` is installed.
* Events are now keyword arguments only
* Restored ``on_precommand`` to its original signature.
* Move ``built_ins.expand_path`` to ``tools.expand_path``.
* Rename ``tools.expandpath`` to ``tools._expandpath``.
* Added ``gvim`` command to unthreadable predictors.
* The ``source`` alias now passes ``$ARGS`` down to file it is sourcing.
**Removed:**
* ``XonshBlockError`` has been removed, since it no longer serves a purpose.
**Fixed:**
* ``PopenThread`` will now re-issue SIGINT to the main thread when it is
received.
* Fixed an issue that using sqlite history backend does not kill unfinished
jobs when quitting xonsh with a second "exit".
* Fixed an issue that xonsh would fail over to external shells when
running .xsh script which raises exceptions.
* Fixed an issue with ``openpty()`` returning non-unix line endings in its buffer.
This was causing git and ssh to fail when xonsh was used as the login shell on the
server. See https://mail.python.org/pipermail/python-list/2013-June/650460.html for
more details.
* Restored the ability to ^Z and ``fg`` processes on posix platforms.
* CommandPipelines were not guaranteed to have been ended when the return code
was requested. This has been fixed.
* Introduce path expansion in ``is_writable_file`` to fix
``$XONSH_TRACEBACK_LOGFILE=~/xonsh.log``.
* Backgrounding a running process (^Z) now restores ECHO mode to the terminal
in cases where the subprocess doesn't properly restore itself. A major instance
of this behaviour is Python's interactive interpreter.
* Readline backend would not ask the user to confirm the printing of completion
options if they numbered above a certain value. Instead they would be dumped to
the screen. This has been fixed.
* Jupyter kernel was no longer properly running subprocess commands.
This has been fixed.
* The filename is applied to the target of the ``source`` alias, providing better
tracebacks.
v0.5.2
====================
**Added:**
* Added ``weechat`` to default predictors
* ``$DYNAMIC_CWD_ELISION_CHAR`` environment variable to control how a shortened
path is displayed.
**Changed:**
* ``_ret_code`` function of ``prompt_ret_code`` xontrib return now ``None`` when
return code is 0 instead of empty string allowing more customization of prompt
format.
**Fixed:**
* Minor Python completer token counting bug fix.
* multiline syntax error in PTK shell due to buffer not being reset
* Segfaults and other early exit signals are now reported correctly,
again.
* ``tests/bin/{cat,pwd,wc}`` shebang changed to python3
v0.5.1
====================
**Fixed:**
* Fixed xonfig raising error when xonsh is not installed from source.
v0.5.0
====================
**Added:**
* $XONTRIB_MPL_MINIMAL environment variable can be set to change if plots are minimalist or as-seen
* xontrib-mpl now supports iTerm2 inline image display if iterm2_tools python package is installed
* Xonsh now will fallback to other shells if encountered errors when
starting up.
* Added entry to customization faq re: ``dirs`` alias (#1452)
* Added entry to customization faq re: tab completion selection (#1725)
* Added entry to customization faq re: libgcc core dump (#1160)
* Section about quoting in the tutorial.
* The ``$VC_HG_SHOW_BRANCH`` environment variable to control whether to hide the hg branch in the prompt.
* xonfig now contains the latest git commit date if xonsh installed
from source.
* Alt+Enter will execute a multiline code block irrespective of cursor position
* Windows now has the ability to read output asynchronously from
the console.
* Use `doctr <https://drdoctr.github.io/doctr/>`_ to deploy dev docs to github pages
* New ``xonsh.proc.uncapturable()`` decorator for declaring that function
aliases should not be run in a captured subprocess.
* New history backend sqlite.
* Prompt user to install xontrib package if they try to load an uninstalled
xontrib
* Callable aliases may now take a final ``spec`` argument, which is the
corresponding ``SubprocSpec`` instance.
* New ``bashisms`` xontrib provides additional Bash-like syntax, such as ``!!``.
This xontrib only affects the command line, and not xonsh scripts.
* Tests that create testing repos (git, hg)
* New subprocess specification class ``SubprocSpec`` is used for specifying
and manipulating subprocess classes prior to execution.
* New ``PopenThread`` class runs subprocesses on a a separate thread.
* New ``CommandPipeline`` and ``HiddenCommandPipeline`` classes manage the
execution of a pipeline of commands via the execution of the last command
in the pipeline. Instances may be iterated and stream lines from the
stdout buffer. These pipelines read from the stdout & stderr streams in a
non-blocking manner.
* ``$XONSH_STORE_STDOUT`` is now available on all platforms!
* The ``CommandsCache`` now has the ability to predict whether or not a
command must be run in the foreground using ``Popen`` or may use a
background thread and can use ``PopenThread``.
* Callable aliases may now use the full gamut of functions signatures:
``f()``, ``f(args)``, ``f(args, stdin=None)``,
``f(args, stdin=None, stdout=None)``, and `
``f(args, stdin=None, stdout=None, stderr=None)``.
* Uncaptured subprocesses now receive a PTY file handle for stdout and
stderr.
* New ``$XONSH_PROC_FREQUENCY`` environment variable that specifies how long
loops in the subprocess framework should sleep. This may be adjusted from
its default value to improved performance and mitigate "leaky" pipes on
slower machines.
* ``Shift+Tab`` moves backwards in completion dropdown in prompt_toolkit
* PromptFormatter class that holds all the related prompt methods
* PromptFormatter caching when building the prompt
* p-strings: ``p'/foo/bar'`` is short for ``pathlib.Path('/foo/bar')``
* byte strings: prefixes other than ``b'foo'`` (eg, ``RB'foo'``) now work
* Backticks for regex or glob searches now support an additional modifier
``p``, which causes them to return Path objects instead of strings.
* New ``BOTTOM_TOOLBAR`` environment variable to control a bottom toolbar as specified in prompt-toolkit
* New ``$XONSH_STDERR_PREFIX`` and ``$XONSH_STDERR_POSTFIX`` environment
variables allow the user to print a prompt-like string before and after
all stderr that is seen. For example, say that you would like stderr
to appear on a red background, you might set
``$XONSH_STDERR_PREFIX = "{BACKGROUND_RED}"`` and
``$XONSH_STDERR_PREFIX = "{NO_COLOR}"``.
* New ``xonsh.pyghooks.XonshTerminal256Formatter`` class patches
the pygments formatter to understand xonsh color token semantics.
* Load events are now available
* New events added: ``on_post_init``, ``on_pre_cmdloop``, ``on_pre_rc``, ``on_post_rc``, ``on_ptk_create``
* Completion for ``xonsh`` builtin functions ``xontrib`` and ``xonfig``
* Added a general customization FAQ page to the docs to collect various
tips/tricks/fixes for common issues/requests
* ``test_single_command`` and ``test_redirect_out_to_file`` tests in ``test_integrations``
* Add note that the target of redirection should be separated by a space.
**Changed:**
* CircleCI now handles flake8 checks
* Travis doesn't allow failures on nightly
* ``get_hg_branch`` runs ``hg root`` to find root dir and check if we're in repo
* The default style will now use the color keywords (#ansired, #ansidarkred)
to set colors that follow the terminal color schemes. Currently, this requires
prompt_toolkit master (>1.0.8) and pygments master (2.2) to work correctly.
* ``vox activate`` now accepts relative directories.
* Updated the effectivity of ``$XONSH_DEBUG`` on debug messages.
* Better documentation on how to get nice colors in Windows' default console
* All custom prompt_toolkit key binding filters now declared with the
``@Condition`` decorator
* The style for the prompt toolkit completion menu is now lightgray/darkgray instead of turquoise/teal
* landscape.io linting now ignores ply directory
* ``history`` help messages to reflect subcommand usage
* Quote all paths when completion if any of the paths needs be quoted,
so that bash can automatically complete to the max prefix of the paths.
* Tee'd reads now occur in 1kb chunks, rather than character-by-character.
* The ``which`` alias no longer has a trailing newline if it is captured.
This means that ``$(which cmd)`` will simply be the path to the command.
* The following commands are, by default, predicted to be not threadable
in some circumstances:
* bash
* csh
* clear
* clear.exe
* cls
* cmd
* ex
* fish
* htop
* ksh
* less
* man
* more
* mutt
* nano
* psql
* ranger
* rview
* rvim
* scp
* sh
* ssh
* startx
* sudo
* tcsh
* top
* vi
* view
* vim
* vimpager
* xo
* xonsh
* zsh
* The ``run_subproc()`` function has been replaced with a new implementation.
* Piping between processes now uses OS pipes.
* ``$XONSH_STORE_STDIN`` now uses ``os.pread()`` rather than ``tee`` and a new
file.
* The implementation of the ``foreground()`` decorator has been moved to
``unthreadable()``.
* ``voxapi.Vox`` now supports ``pathlib.Path`` and ``PathLike`` objects as virtual environment identifiers
* Renamed FORMATTER_DICT to PROMPT_FIELDS
* BaseShell instantiates PromptFormatter
* readline/ptk shells use PromptFormatter
* Updated the bundled version of ``ply`` to current master available
* vended ``ply`` is now a git subtree to help with any future updates
* ``WHITE`` color keyword now means lightgray and ``INTENSE_WHITE`` completely white
* Removed ``add_to_shell`` doc section from ``*nix`` install pages and instead
relocated it to the general customization page
* Moved a few ``*nix`` customization tips from the linux install page to the general
customization page
**Removed:**
* coverage checks
* ``CompletedCommand`` and ``HiddenCompletedCommand`` classes have been removed
in favor of ``CommandPipeline`` and ``HiddenCommandPipeline``.
* ``SimpleProcProxy`` and ``SimpleForegroundProcProxy`` have been removed
in favor of a more general mechanism for dispatching callable aliases
implemented in the ``ProcProxyThread`` and ``ProcProxy`` classes.
* ``test_run_subproc.py`` in favor of ``test_integrations.py``
* Unused imports in many tests
* Many duplicated tests (copypasta)
**Fixed:**
* xontrib-mpl now preserves the figure and does not permanently alter it for viewing
* Fix up small pep8 violations
* Fixed a bug where some files are not showing using bash completer
* Fixed some issues with subprocess capturing aliases that it probably
shouldn't.
* ``safe_readable()`` now checks for ``ValueError`` as well.
* The scroll bars in the PTK completions menus are back.
* Jupyter kernel installation now respects the setuptools ``root`` parameter.
* Fix ``__repr__`` and ``__str__`` methods of ``SubprocSpec`` so they report
correctly

* Fixed a handful of sphinx errors and warnings in the docs
* Fixed many PEP8 violations that had gone unnoticed
* Fix failure to detect an Anaconda python distribution if the python was install from the conda-forge channel.
* current_branch will try and locate the vc binary once
* May now Crtl-C out of an infinite loop with a subprocess, such as
```while True: sleep 1``.
* Fix for stdin redirects.
* Backgrounding works with ``$XONSH_STORE_STDOUT``
* ``PopenThread`` blocks its thread from finishing until command has completed
or process is suspended.
* Added a minimum time buffer time for command pipelines to check for
if previous commands have executed successfully. This is helpful
for pipelines where the last command takes a long time to start up,
such as GNU Parallel. This also checks to make sure that output has occurred.
This includes piping 2+ commands together and pipelines that end in
unthreadable commands.
* ``curr_branch`` reports correctly when ``git config status.short true`` is used
* ``pip`` completion now filters results by prefix
* Fixed streaming ``!(alias)`` repr evaluation where bytes where not
streamed.
* Aliases that begin with a comma now complete correctly (no spurious comma)
* Use ``python3`` in shebang lines for compatibility with distros that still use Python 2 as the default Python
* STDOUT is only stored when ``$XONSH_STORE_STDOUT=True``
* Fixed issue with alias redirections to files throwing an OSError because
the function ProcProxies were not being waited upon.
* Fixed issue with callable aliases that happen to call sys.exit() or
raise SystemExit taking out the whole xonsh process.
* Safely flushes file handles on threaded buffers.
* Proper default value and documentation for ``$BASH_COMPLETIONS``
* Fixed readline completer issues on paths with spaces
* Fix bug in ``argvquote()`` functions used when sourcing batch files on Windows. The bug meant an extra backslash was added to UNC paths.
Thanks to @bytesemantics for spotting it, and @janschulz for fixing the issue.
* pep8, lint and refactor in pytest style of ``test_ptk_multiline.py``, ``test_replay.py``
* Tab completion of aliases returned a upper cased alias on Windows.
* History show all action now also include current session items.
* ``proc.stream_stderr`` now handles stderr that doesn't have buffer attribute
* Made ``history show`` result sorted.
* Fixed issue that ``history gc`` does not delete empty history files.
* Standard stream tees have been fixed to accept the possibility that
they may not be backed by a binary buffer. This includes the pipeline
stdout tee as well as the shell tees.
* Fixed a bug when the pygments plugin was used by third party editors etc.
* CPU usage of ``PopenThread`` and ``CommandPipeline`` has been brought
down significantly.

**Changed:**
* Devguide reflects the current process of releasing through ``release.xsh``
* moved ``which`` from ``xonsh.aliases`` into ``xoreutils.which``
* ``xonsh.prompt.gitstatus.gitstatus`` now returns a namedtuple
* implementation of ``xonsh.prompt.vc_branch.get_git_branch`` and
``xonsh.prompt.vc_branch.git_dirty_working_directory`` to use 'git status --procelain'
* moved prompt formatting specific functions from ``xonsh.environ``
to ``xonsh.prompt.base``
* All prompt formatter functions moved to ``xonsh.prompt`` subpackage
* Printing the message about foreign aliases being ignored happens only
if XONSH_DEBUG is set.
* Use ``SetConsoleTitleW()`` on Windows instead of a process call.
* Tutorial to reflect the current history command argument functionality
* Macro function arguments now default to ``str``, rather than ``eval``,
for consistency with other parts of the macro system.
**Removed:**
* aliases that use '!' in their name cause they clash with the macro syntax
**Fixed:**
* Fix regression where bash git completions where not loaded
automatically when GitForWindows is installed.
* More tokens are now supported in subproc args, such as ``==``.
* Python completions now work without space delimiters, e.g. ``a=matpl<TAB>``
will complete to ``a=matplotlib``
* Parser would fail on nested, captured suprocess macros. Now, it works,
hooray!?
* now fires chdir event if OS change in working directory is detected.
* ``xonsh.prompt.vc_branch.git_dirty_working_directory``
uses ``porcelain`` option instead of using the bytestring
``nothing to commit`` to find out if a git directory is dirty
* Fix bug where know commands where not highlighted on windows.
* Fixed completer showing executable in upper case on windows.
* Fixed issue where tilde expansion was occurring more than once before an
equals sign.
* test_dirstack test_cdpath_expansion leaving stray testing dirs
* Better completer display for long completions in prompt-toolkit

* Fixed issue with accidentally wrapping generators inside of function calls.
* History indexing with string returns most recent command.
v0.4.6
====================
**Added:**
* New option ``COMPLETIONS_CONFIRM``. When set, ``<Enter>`` is used to confirm
completion instead of running command while completion menu is displayed.
* NetBSD is now supported.
* Macro function calls are now available. These use a Rust-like
``f!(arg)`` syntax.
* Macro subprocess call now available with the ``echo! x y z``
syntax.
* A new `event subsystem <http://xon.sh/tutorial_events.html>`_ has been added.
* howto install sections for Debian/Ubuntu and Fedora.
* ``History`` methods ``__iter__`` and ``__getitem__``
* ``tools.get_portions`` that yields parts of an iterable
* Added a py.test plugin to collect ``test_*.xsh`` files and run ``test_*()`` functions.
* ``__repr__`` and ``__str__`` magic method on LazyObject
**Changed:**
* ``create_module`` implementation on XonshImportHook
* Results of the ``bash`` tab completer are now properly escaped (quoted) when necessary.
* Foreign aliases that match xonsh builtin aliases are now ignored with a warning.
* ``prompt_toolkit`` completions now only show the rightmost portion
of a given completion in the dropdown
* The value of ``'none'`` is no longer allowed for ``$SHELL_TYPE`` just during the initial
load from the environment. ``-D``, later times, and other sources still work.
* ``yacc_debug=True`` now load the parser on the same thread that the
Parser instance is created. ``setup.py`` now uses this synchronous
form as it was causing the parser table to be missed by some package
managers.
* Tilde expansion for the home directory now has the same semantics as Bash.
Previously it only matched leading tildes.
* Context sensitive AST transformation now checks that all names in an
expression are in scope. If they are, then Python mode is retained. However,
if even one is missing, subprocess wrapping is attempted. Previously, only the
left-most name was examined for being within scope.
* ``dirstack.pushd`` and ``dirstack.popd`` now handle UNC paths (of form ``\\<server>\<share>\...``), but only on Windows.
They emulate behavior of `CMD.EXE` by creating a temporary mapped drive letter (starting from z: down) to replace
the ``\\<server>\<share>`` portion of the path, on the ``pushd`` and unmapping the drive letter when all references
to it are popped.
* And ``dirstack`` suppresses this temporary drive mapping funky jive if registry entry
``HKCU\software\microsoft\command processor\DisableUNCCheck`` (or HKLM\...) is a DWORD value 1. This allows Xonsh
to show the actual UNC path in your prompt string and *also* allows subprocess commands invoking `CMD.EXE` to run in
the expected working directory. See https://support.microsoft.com/en-us/kb/156276 to satisfy any lingering curiosity.
* ``lazy_locate_binary`` handles binary on different drive letter than current working directory (on Windows).
* ``_curr_session_parser`` now iterates over ``History``
* New implementation of bash completer with better performance and compatibility.
* ``$COMPLETIONS_BRACKETS`` is now available to determine whether or not to
include opening brackets in Python completions
* ``xonsh.bat`` tries to use `pylauncher <https://www.python.org/dev/peps/pep-0397/>`_ when available.
**Removed:**
* ``History`` method ``show``
* ``_hist_get_portion`` in favor of ``tools.get_portions``
* Unused imports in proc, flake8.
**Fixed:**
* xonsh modules imported now have the __file__ attribute
* Context sensitive AST transformer was not adding argument names to the
local scope. This would then enable extraneous subprocess mode wrapping
for expressions whose leftmost name was function argument. This has been
fixed by properly adding the argument names to the scope.
* Foreign shell functions that are mapped to empty filenames no longer
receive aliases since they can't be found to source later.
* Correctly preserve arguments given to xon.sh, in case there are quoted ones.
* Environment variables in subprocess mode were not being expanded
unless they were in a sting. They are now expanded properly.
* Fixed a bug that prevented xonsh from running scripts with code caching disabled.
* Text of instructions to download missing program now does not get off and
appears in whole.
* Fix some test problems when win_unicode_console was installed on windows.
* Fixed bug that prompt string and ``$PWD`` failed to track change in actual working directory if the
invoked Python function happened to change it (e.g via ```os.chdir()```. Fix is to update ``$PWD``
after each command in ```BaseShell.default()```.
* The interactive prompt now correctly handles multiline strings.
* ``cd \\<server>\<share>`` now works when $AUTO_PUSHD is set, either creating a temporary mapped drive or simply
setting UNC working directory based on registry ``DisableUNCCheck``. However, if $AUTO_PUSHD is not set and UNC
checking is enabled (default for Windows), it issues an error message and fails. This improves on prior behavior,
which would fail to change the current working directory, but would set $PWD and prompt string to the UNC path,
creating false expectations.
* fix parsing for tuple of tuples (like `(),()`)
* ``sys.stdin``, ``sys.stdout``, ``sys.stderr`` no longer complete with
opening square brackets
* xonsh now properly handles syntax error messages arising from using values in inappropriate contexts (e.g., ``del 7``).
Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.
xonsh is a Python-ish, BASHwards-looking shell language and command prompt. The
language is a superset of Python 3.4+ with additional shell primitives. xonsh
(pronounced conch) is meant for the daily use of experts and novices alike.
